was able to / managed to We tend to use was able to or managed to if we are talking about what happened in a particular situation or are referring to a specific achievement (we can’t use COULD): Were you able to / Did you manage to speak to him before he left home? ~ No, I'm sorry, I wasn't able to / didn't manage to reach him. 9/4/20154
